ALT; Alanine Aminotransferase; SGPT


The alanine aminotransferase (ALT) test is a blood test that checks for liver damage. Your doctor can use this test to find out if a disease, drug, or injury has damaged your liver.

Your liver does a lot of important things for you: 

  • It makes a fluid called bile that helps your body digest food.
  • It removes waste products and other toxins from your blood.
  • It produces proteins and cholesterol.


Diseases such as hepatitis and cirrhosis can damage your liver and prevent it from doing its many jobs.

This enzyme is found mainly in your liver. Smaller amounts of ALT are in your kidneys and other organs, too.

Your body uses ALT to break down food into energy. Normally, ALT levels in the blood are low. If your liver is damaged, it will release more ALT into your blood and levels will rise. (ALT used to be called serum glutamic-pyruvic transaminase, or SGPT).
